SDIFF(1)                COMMAND REFERENCE                SDIFF(1)



NAME
     sdiff - side-by-side difference program

SYNOPSIS
     sdiff [ -w n ] [ -l ] [ -s ] [ -o output ] filename1
     filename2

DESCRIPTION
     Sdiff uses the output of diff(1) to produce a side-by-side
     listing of two files indicating those lines that are
     different.  Each line of the two files is printed with a
     blank gutter between them if the lines are identical, a < in
     the gutter if the line only exists in filename1, a > in the
     gutter if the line only exists in filename2, and a | (pipe)
     for lines that are different.  (See EXAMPLES Section.)

OPTIONS
     -l Only print the left side of any lines that are identical.

     -o output
        Use the next argument, output, as the name of a third
        file that is created as a user-controlled merging of
        filename1 and filename2.  Identical lines of filename1
        and filename2 are copied to output.  Sets of differences,
        as produced by diff(1), are printed where a set of
        differences share a common gutter character.  After
        printing each set of differences, sdiff prompts the user
        with a % and waits for one of the following user-typed
        commands:

          l  Append the left column to the output file

          r  Append the right column to the output file

          s  Turn on silent mode; do not print identical lines

          v  Turn off silent mode

          e l
             Call the editor with the left column

          e r
             Call the editor with the right column

          e b
             Call the editor with the concatenation of left and
             right

          e  Call the editor with a zero length file

          q  Exit from the program

        On exit from the editor, the resulting file is
        concatenated on the end of the output file.

        The editor used will be determined by the value contained
        in the environment variable EDIT.  If it has not been
        set, ed is used by default.

     -s Do not print identical lines.

     -w n
        Use the next argument, n, as the width of the output
        line.  The default line length is 130 characters.

EXAMPLES
     Given the file foo.1 composed of the letters x, a, b, c, and
     d on individual lines, and the file foo.2 similiarly
     composed of the letters y, a, d, and c,  the following
     results will ocurr:

          sdiff foo.1 foo.2
          x                    | y
          a                      a
          b                    <
          c                    <
          d                      d
                               > c

VARIABLES
     EDIT           The editor to be used with the -o option.

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [NP_WARN]      An error warranting a warning message
                    occurred. Execution continues.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

CAVEATS
     Sdiff executes diff(1) in order to process the input files.
     If a line coming from diff is longer than 200 characters, an
     error message is printed and sdiff exits.

SEE ALSO
     diff(1), ed(1), and sh(1sh).
